This is INSANE. 30 layers, 30th birthday.I just used box white cake mixes - 10 of them that I bought on sale. I had 6 6x6 cake pans and I mixed and baked 2 cake mixes at a time, divided them into 6 bowls and mixed in Wilton gel food coloring bought at JoAnns. Cool idea for a rainbow party too...but with scratch cake.
this site has really hilarious game ideas for adults and kids. they can be used for birthdays or just a fun game night. love it!
